A proteomic approach for studying insect phylogeny: CAPA peptides of ancient insect taxa (Dictyoptera, Blattoptera) as a test case
This study concludes that sequences of short neuropeptides are suitable to complement molecular biological and morphological data for the reconstruction of phylogenetic relationships within higher taxa.

This study is the first to use semi-field experiments in a strawberry field, manipulating densities, to investigate how P. melanarius and C. nemoralis affect densities of A. vulgaris eggs and juveniles, respectively.

The unique accumulation of these FMRFamide‐related peptides in thoracic perisympathetic organs provides the definite evidence for a tagma‐specific distribution of peptidergic neurohormones in neurohaemal release sites of the insect CNS.
Tachykinin‐related peptide precursors in two cockroach species
Mass spectrometric analysis demonstrated the occurrence of the different TKRPs in single glomeruli of the tritocerebrum and in cells of the optical lobe and the data do not suggest a differential gene expression but a different efficacy in processing of LemTKRP‐2 and Lem/PeaTK RP‐3 in the brain and intestine, respectively.
Bedbugs Evolved before Their Bat Hosts and Did Not Co-speciate with Ancient Humans
Molecular evidence places the swallow bug genus Oeciacus Stål within the bat and bed bug genus Cimex Linnaeus (Heteroptera: Cimicidae)
The present analyses recovered the four traditional morphologically defined species groups of the genus Cimex and suggest poly‐ or paraphyly of the former genus Oeciacus, which indicates there is a large amount of host‐associated phenotypic convergence in either bat‐ or bird‐associated groups of species.
Biodiversity, ecology, and behavior of the recently discovered insect order Mantophasmatodea
This work collected and analyzed numerous populations that belong to all known mantophasmatodean lineages, including East African populations, to provide a comprehensive biogeographical overview and a comparative analysis of behavior, which was mainly analyzed under laboratory conditions.
Peptidomics-based phylogeny and biogeography of Mantophasmatodea (Hexapoda).

The data confirm the monophyly of Austrophasmatidae and show a relatively recent and extensive radiation in the winter rainfall region of South Africa but also suggest that the species-level diversification of Namibian Mantophasma is less marked than previously thought.
Functional analysis by trophic guilds of macrobenthic community structure in Dublin Bay, Ireland
New insect order Mantophasmatodea: species differentiation by mass fingerprints of peptide hormones?
The methodological approach underlying this application resulted in the first completely sequenced peptide hormones of the Mantophasmatodea, namely adipokinetic hormone, leucomyosuppressin, and a novel member of the periviscerokinins.
